Multi-scale Modelling of Sintering
Sintering models at the atomistic, particle and component scales are briefly reviewed and problems in the current generation of sintering models are highlighted. A strategy of multi-scale modelling is proposed and our progress in the multiscale modelling is reported. Mathematical details of the models are left out and the paper is set out to demonstrate what is possible in the next generation o...
متن کاملNumerical Modelling in a Multi-Scale Ocean
Systematic improvement in ocean modelling and prediction systems over the past several decades has resulted from several concurrent factors. The first of these has been a sustained increase in computational power, as summarized in Moore’s Law, without which much of this recent progress would not have been possible. Despite the limits imposed by existing computer hardware, however, significant a...
متن کاملMulti-scale modelling in computational biomedicine
The inherent complexity of biomedical systems is well recognized; they are multi-scale, multi-science systems, bridging a wide range of temporal and spatial scales. This article reviews the currently emerging field of multi-scale modelling in computational biomedicine. Many exciting multi-scale models exist or are under development. However, an underpinning multi-scale modelling methodology see...
متن کاملA framework for multi-scale modelling.
We review a methodology to design, implement and execute multi-scale and multi-science numerical simulations. We identify important ingredients of multi-scale modelling and give a precise definition of them. Our framework assumes that a multi-scale model can be formulated in terms of a collection of coupled single-scale submodels. With concepts such as the scale separation map, the generic subm...
متن کاملMulti-scale modelling of damage and fracture
Recently, a novel multi-scale modelling approach for damage and fracture problems was presented. This method departs from classical computational homogenization (FE) and evolves to a discontinuity enriched scheme upon the localization detection. Rotating boundary conditions allow for microscale localization bands to develop. The formulation of the macroscopic cohesive discontinuity enables the ...
